PROBLEM TO BE SOLVED: To provide a construction method of securing water permeability of a water-bearing layer which can easily prevent an abnormal rise in the ground water level on the upstream side of the water-bearing layer which is interrupted by an underground continuous wall, or the occurrence of damage such as the exhaustion of water in a well, ground subsidence or the like on the downstream side, and which can easily take measures against clogging. SOLUTION: The underground continuous wall 1 is formed in the ground which is comprised of a soil cement wall body 11 and a core material 12. Then openings 12a, 11a are formed on the core material 12 and the soil cement wall body 11 from the center side of the core material 12 in the position where the water-bearing layer WS is interrupted by the underground continuous wall 1. Then a removable permeable filter member 13 is arranged on the core material 12 on which the opening 12a is formed. Thus, water permeability of the water-bearing layer WS which is interrupted by the underground continuous wall 1 is secured. COPYRIGHT: (C)2006,JPO&NCIPI
